I have a 95 silverado c1500 with 4l60e trans and it wont go into overdrive


overdrive is the fourth gear.D1,D2,D3,D4 now drive truck at 80 kmh
cruise at steady speed no fuel pedal movement, downshift from D4 to D3 you should feel RPM raise .. after push brake pedal a little you should see RPM raise 300 to 400 rpm.
shift pattern is 1st gear ,second gear,3rd gear and lock up(torque converter clutch). 4th gear with lock up
hope it helps

How do i tell if my transmission is a automatic 4 or 5 or 6 speed? on a 2006 frontier se 4 x 4 engine code: re5ro5a


If it's an automatic, You see the Following: P R N D 2 1 etc. Some may show: P R N D 3 2 1 or .... 3 2 L ... D 2 L etc.

To really determine whether it's a 4,5 or 6, take into consideration if it has Overdrive.

Count however many gears are on the column, as listed above, plus overdrive. this will give you your answer.

Ex: With Overdrive: P R N D 3 2 would be a 3 speed ( 2 3 D) with overdrive.

Reset code trailer towing may set code gm 4l60E


Diagnostic trouble code P1870 (Transmission Component Slippage) is a General Motors-specific code whose set parameters are determined by transmission type and engine size. The PCM monitors and compares engine speed to vehicle speed after the converter clutch has been commanded ON in either high gear or Overdrive. Should the expected rpm ratio exceed predetermined parameters, DTC 1870 sets. And upon doing so, the PCM elevates the transmission main line pressure and stops converter clutch apply.

Once the vehicle has made it to a cruise state, the PCM then begins to monitor the vehicle's cruise ratio. If at some point the transmission begins to slip, P1870 sets and line pressure is elevated in an attempt to stop any further slippage and prevent further damage. This would explain why DTC 1870 Ls often accompanied by a complaint of a hard 1-2 up shift.

When this code sets, it could have any number of causes, ranging from the sump running low of fluid to a malfunctioning torque converter. Take a GM 4L60-E transmission, for example. When it's in Overdrive, the forward clutch and the 3-4 clutches are applied, as well as the 2-4 band. Now add the converter clutch. This is what the PCM monitors at cruise. If the ratio breaks away, the cause could be any of three components, the hydraulics that operate them or the electronics that control them. Fortunately, experience has shown that in most cases, the cause can be traced to some form of converter clutch failure as a result of valve body concerns. With GMs 4L80-E transmission, this code has usually been the result of a cracked converter clutch piston.

Put a line pressure gauge ($55 shipped on Ebay, or visit a local trans shop) on the pressure test port and go for a drive to verify proper line pressure. Base pressure at idle in P,N,OD should be around 70psi and around 140psi in R. Max line pressure should be at least 190psi at WOT in 1st or 2nd, 225psi is optimum. If base pressure is low, trans or pump is worn out. If max pressure is low, check EPC solenoid. If reverse is slow to engage, and line pressure does not come up to at least 130psi in reverse, replace the boost valve with a Transgo 0.049" - 0.500" boost valve (easy fix in pan), and replace the servo with an upgrade servo from a Corvette 4L60E. This will give you a more firm shift and address the DTC 1870 which is common to a weaken Boost valve or faulty EPC valve.

2005 ford ranger 4L 4x4 overdrive does not engage when button on shifter is pushed. I also do not see the light on the cluster on


If you have it in 4 LOW, you would never need overdrive. Overdrive is a road high gear that you would use only in 4 HIGH (or 4H) on your shifter. 4L (or 4 Low) would only be used in a very slow speed hill climb. You would NEVER use 4 Low on the road.

1995 chevrolet 3500 transmission


I own a shop, and think you should have a 4L-60 in it. These look just like a 700 R-4, but aren't. There isn't much difference in them, but according to my books it should have the 4l60, but some were 4l80. The 4l80 was mostly for the diesel engines though. Glad to help out, Good Luck!!!
